JOAQUIN ROVIRA, 0F MAINZ, AND HERMANN AHRLE, QF FRANKFORT-ON-THE-MAI'N, GERMANY; SAID AHRLE ASSIGNOR TO SAID ROVIRA.

MOU'IHPIECE FOR CIGARETTES.

To all whom it may concern Be it known that we, JOAQUIN ROVIRA, a subject of the King of Spain, residing at Mainz, Germany, and HERMANN AHRLE, a subject of the Emperor of Germany, residing at Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Mouthpieces for Cigarettes, of which the following is a true and complete specification.

The present invention relates to improvements in cork mouth pieces of cigarettes.

The known mouth pieces of cigarettes or the like covered with cork are made by using leaves of cork obtained by splitting normal leaves or by cutting them in a well known manner. Such mouth pieces are very dear as they require the best leaves of cork material and such leaves are limited moreover in length and breadth, and do not entirely comply with the conditions required for good mouth pieces. The most important disadvantage of the cork mouth pieces is their containing larger or smaller perforations, chinks, splits or the like in consequence of which the humidity to be retained within the tobacco may escape and also inversely humidity, for instance the spittle of the smoker, may enter the tobacco. F urthermore, the leaves of cork having projecting parts when in place on the mouth piece cause the cigarettes to be retained Within the machines for making them instead of passing through them in continuous running. Another great disadvantageof the known cork mouth pieces in their being somewhat thicker than the cigarettes themselves, as, in order to obtain mouth pieces of the solidity required, the cork plating must be made of a certain thickness. In consequence of this the packages of such cigarettes are thicker on the one end than on the other one and the middle parts of the cigarettes do not touch one another so that the cigarettes may easily be broken there, and the appearance of such packages is not agreeable.

The present invention dispenses with all the disadvantages stated above and relates to a cork mouth piece showing all the advantages of the known cork mouth pieces and on the other hand is freefrom all disadvantages of such known mouth pieces and nevertheless is cheaper and more solid.

A cigarette prepared according to the in- Patented Sept. 14L, 19115.

Application filed January 8, 1915. Serial No. 1,223.

vention is shown in the accompanying drawing some parts of the mouth pieces being broken away.

The material used for the mouth pieces according to our invention is flour of cork and is very cheap, being made-of waste or chips of cork instead of best leaves of cork. Such flour is spread out in a very thin continuous layer upon a strip or breadth of a thin suitable material, preferably paper, suitably prepared for retaining said flour. For instance said paper is covered with a very thin coat of a liquid not drying before a certain time has elapsed after being coated on the paper and showing a surface adapted to keep said layer of cork flour firmly before drying and retaining it also after drying. After application to the paper the liquid is allowed to dry to a certain degree and the cork flour applied thereto. The liquid is of such character, however, that the artial drying just mentioned does not a ect its adhesiveness. The liquid preferably used is a varnish composed of one hundred parts of benzin, three to six parts of Para-gum and about ten parts of zapon varnish, said varnish consisting of celluloid dissolved in amyl acetate and acetone. This adhesive is very' elastic and completely water proof when dried and is a very thin layer with cork flour which should by no means project from the cigarette mouth piece or paper.

The cork flour not retained or accepted by the fixing liquid may be removed by Wiping or brushing or the like so that the remaining layer will be very thin and of perfect continuity. In order to accelerate drying and to fix cork flour as much as possible the breadth prepared and fitted with flour may pass between rollers which may be heated if required, 6. 6. it is calendered. On the accompanying drawing 1 is the cigarette provided with a mouth piece 2 according to the invention. The said mouth piece is covered with a thin layer 3 of adhesive upon which the layer 5 of flour of cork maybe placed and fixed as stated above.

In order to make the layer of cork appear more as if of cork leaf, it may be provided with punctuations, drawings of chinks, fissures and the like and other drawingsshowing the natural structure of cork leaves, and with regard to the layer being very thin and even transparent it is preferable to have the mouth pieces made of paper the color 'phone simply takes off the receiver and the mechanism actuates the switch and puts the light 22 on and when he hangs up the receiver the light is switched off by the same mechanism or if the lever 18 and its connecting parts are not in use, the subscriber simply moves the switch handle up and down with his finger.

While but a general form of the invention is shown in the drawings it is not desired to limit this application for patent, to that particular form or in any other way except as limited by the priorart, as many modifications in this invention may be made without departing from the principles thereof and coming within the scope of the appended claims.

Having thus described the invention what is claimed is:

1. In combination with a telephone standard or a telephone case, a battery, a casing for the battery, a socket on the casing, a lamp in the socket, a sliding switch in the casing adapted to connect the battery and socket in circuit with each other, a clamp arranged to embrace the standard or case, and a lever mechanism pivotally connected to the clamp, adapted to actuate the switch when the telephone apparatus is put in and out of use.

2. In combination with a telephone set a battery, a casing for the battery, :1. socket on the casing, a lamp in the socket, a sliding switch in the casing adapted to connect the battery and socket in circuit with each other, a clamp arranged to embrace the set, means for securing the clamp and casing together, a lever mechanism pivoted to the clamp, a plurality of catches on the lever mechanism adapted to be slid on and oil the receiver mechanism of the set and the switch, whereby the same may be or may not be connected to work in unison.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.

ARTHUR E. HOWARD, Mrs. GRAY BEMIS.
